• W2903453370 abstract "BackgroundPatent foramen ovale (PFO) is present in as many as 25% of the general population and is considered an irrelevant condition in healthy subjects. Here, we sought to determine an association between an asymptomatic PFO at baseline and postoperative short-term adverse events in patients undergoing major pulmonary resection for lung cancer. In addition, we evaluated for the rate of PFO after pulmonary resections.MethodsThis prospective, observational study assessed patients by transcranial Doppler with contrast at baseline and discharge. To confirm interatrial shunting, patients with positive transcranial Doppler at baseline also underwent contrast transthoracic echocardiography. Multivariate logistic regression models were adopted to investigate for independent factors that could have been associated with complications. Backward stepwise procedure was used for model selection.ResultsMedian age was 67.7 ± 9.2 years (range, 36 to 86), and 67% were men. Overall, 18 patients underwent pneumonectomy, 11 bilobectomy, and 118 lobectomy; 54% underwent right-sided procedure and 46%, left-sided. One perioperative death was recorded, and 34 patients had one or more cardiopulmonary complications. At baseline, PFO was positive in 25% (37 of 147) and negative in 75% (110 of 147); of the latter, 11% were positive at discharge. Detection of PFO at baseline, on multivariate analysis, was significantly associated with a risk of postoperative complications (odds ratio 2.5; 95% confidence interval: 1.1 to 5.8). Specifically, we observed a significant association between atrial fibrillation and positive PFO at baseline (odds ratio 3.5; 95% confidence interval: 1.4 to 9.0).ConclusionsPreoperative asymptomatic PFO was independently associated with postoperative adverse events. Moreover, 11% of patients who had negative transcranial Doppler studies at baseline had asymptomatic PFOs at discharge. Larger prospective studies are needed to further investigate for a prognostic impact of PFO in thoracic surgery.
